Hi Bj�rn,

I had a similar problem with my '87 GL. Turned out to be an overflow tank 
with a hairline crack underneath (patched with duct tape by PO). I could not 
find any water leaking but always smelled like coolant around the rear. 
Finally, I took the cooling components apart one at a time until I found the 
culprit. $26 from the local VW dealer and I was ready to go.
